Is it time to change...

my plugs, wires, and coils? My 04' MT currently has 60,XXX miles. The last time I had my plugs changed was when the dealer did it for the Flooding recall back in the day at about 20,XXX miles. I am still on my original sets of coils and wires. I'm not experiencing any misfires, but I'm sure if I changed the plugs, coils, wires I'd probably improve performance. I would really like to do this all in one job and in one day. Is it too early to tackle this project considering I'm not having any problems? Should I wait for 70,000 miles or more??

Ok follow up question. Say after I do this job, my plugs will last to 100K miles. How long do I wait to change the wires and coils again? (Assuming I still have the car)

Wow,

You're @ 60K right ? I will change them again no later than 80K.

Hmmm. Always thought the plugs were good for 35K-50K miles??

From what I've read on here, 35k miles would be on the high side for the renesis.

wires don't really wear out, its just a piece of wire after all. How often do you change the wires in your house? Your tv? the rest of your car? Replace them if they are getting corrosion on the contacts or they are looking frayed.

Personally, I would wait until problems arise then drop the cash on the coil upgrade.

Wires DO wear out. Corrosion builds up on the contacts (among other things), and over time their resistance increases. I blew out the ignition control module twice on my old honda because i had bad plug wires. They had to high a resistance and caused the control module to pull to much current, burning it out. That lesson cost me 800 bucks (those chips aren't cheap! Especially not 2 in a 6 month period)

I also would be overdue then.

How hard is it to change plugs wires and coil? How much would it cost at a dealer vs doing it myself?

Wires do wear out.

The reason why we hardly replace our home wires every year simply because it will never be exposed to all the stuff u see on the outside, it stays in ur walls, nice and cool, no sunlight, probably never see oil, no extended periods of heat, no dirt,etc .

Wires just like most metal, will break, just a matter of time, and the process accelerate if it has been exposed to all the crap I said above,

The coil is the 4 blocks of *black thing* under the intake tube. You need a 10mm socket, extension bar, and a socket wrench.

The wires is just plug and play, if u know how to open your door Im sure u will know how to do it. Just remember the order of the plug and u'll be fine.

Dealership cost? hmm, for me I will do the plugs at the same time. I take my time and usually within an hour. but Im pretty sure dealership will charge you at LEAST 2 hours. and the parts will be at LEAST double of what we can get here or anywhere on the internet. You can do the rest of the math yourself.

but I just gotta say, the price you pay dealership to do it, can buy you "at least" another set of Coils + Plug wires + 4 brand new plugs for your next change.

Most people say they want dealership to do it simply because "I dont have the time".

Dont have the time my ***, sure you dont have that 1 hour outa every 6 months or a year on your car, while you have hundreds and hundreds of hours to do other useless crap.

So by your logic we should also replace the rest of the wires in the car?

Just like I said in my first post, replace them if they are corroded, but theirs no reason they should be corroded unless a person isn't putting the plug boots on fully.

Thanks.

I have done plugs on other vehicles, but I guess my main concern is how difficult, or special it is to change the plugs themselves on the rotary. .If theres nothing that difficult to it, I need to do mine...Really Bad!

The reason why we dont have to replace most of the wires in our car is because they're been shielded, well, wrap around in layers of tape for that reason.

there are only a few wires that will expose to road dirt and stuff, plug wires are one of them.

Some plug wires like the RB one, you cant plug the boots in fully, u will leave something open. Thats probably one of the reasons why I dont like RB wires. I mean yes they're high quality but ...
